What keeps igloo houses warm?
It’s an insulation thing. Igloos are built from compressed snow. While it looks solid, as much as 95% of snow is actually air trapped inside tiny crystals. Because the air can’t circulate very well inside the ice crystals, the heat gets trapped in there.

Can you have a fire in an igloo?
But while a central fire will always deliver some heat to the ice of the igloo, the ice of the igloo will also tend to lose heat to colder air outside. As long as the ice loses heat at least as fast as the fire delivers heat to it, the ice won’t become any warmer and it won’t melt.
Can you suffocate in an igloo?
